Scientists map part of a mouse’s brain

Using a piece of that mouse’s brain about the size of a poppy seed, the researchers identified those neurons and traced how they communicated via branch-like fibers through a surprising 500 million junctions called synapses.

“It definitely inspires a sense of awe, just like looking at pictures of the galaxies,” said Forrest Collman of the Allen Institute for Brain Science in Seattle, one of the project’s leading researchers. “You get a sense of how complicated you are. We’re looking at one tiny part ... of a mouse’s brain and the beauty and complexity that you can see in these actual neurons and the hundreds of millions of connections between them.”
